Let me start with, thanks for this amazing addition to our toy collections!!! We really do all appreciate all of the plugin creators time and talents and don't say it enough.
Just one small thing i noticed. I use Celsius for Nest Home and when I have Siri change the temp, it cranks it up all the way. I think what it may be doing is hearing 21 decrees and setting it to 70 (21 Celsius is 70 Fahrenheit). Since my Nest is in Celsius, it wants to make it a sauna at 70 Celsius. It worked as it should just using the homebridge-Indigo plugin, so i think its specific to HBB.
I think we either need a Celsius/Fahrenheit setting in the config screen. In the mean time, where is the new location for the .json file that the HBB creates and uses? I'll have a look there if i can change it.
